There had been quite a lot of cirrocumulus cloud mixed with high cirrus clouds crossing the sky today which always makes me keep an eye out for atmospheric phenomena of any kind…especially Sundogs and solar halo’s.

But today I got a real treat; not only was there a lovely Sundog in the sky, there were also these unusual soft pastel streaks of thin coloured cloud between thicker layers of clouds, they were very pretty and striking in colour.

The colours are caused by the light from the Sun being diffracted out in the sky by the tiny ice crystals in the thin cirrus cloud which creates this rainbow like effect…it’s the first time I’ve ever seen it spread out so far across the sky like this :-)
